Clear wsrep XID in innobase_rollback_by_xid() for recovered wsrep transaction in order to avoid resetting XID storage when rolling back wsrep transaction during recovery. Sort wsrep XIDs read from storage engine in ascending order and erify that the range is continuous during crash recovery. If binlog is off, commit all recovered transactions for continuous seqno range. This is safe because all transactions with wsrep XID have been certified and must be committed in the cluster. On the other hand if binlog is on, respect binlog as a transaction coordinator in order to avoid missing transactions in binlog that have been committed into storage engine .
